Can Surgical Navigation Reduce Radiation Exposure in Spinal Fusion? Let’s Explore
Performing a spinal fusion and screw fixation with precision and safety can be extremely challenging, especially in complex spinal deformities. This is where CT-based surgical navigation plays a vital role.
Why Surgical Navigation Matters in Spinal Procedures
Surgical navigation tools offer:
- Real-time guidance and precision
- Accurate pedicle screw placement
- Pre-operative CT-based planning that enhances visualization
- Reduced chances of implant-related complications
- Improved outcomes without rework
By using this technology, surgeons can confidently place screws and rods according to the patient’s exact anatomical structure.
The Challenge of Anatomical Variability in Spine Surgeries
Spinal anatomy, especially pedicle size and shape, varies significantly due to:
- Anatomical differences
- Degenerative changes
- Osteoporotic bone density
These factors make pedicle screw fixation more complex, especially in the thoracic region. Fluoroscopy may assist, but it brings added challenges.
Limitations of Fluoroscopy
Although fluoroscopy can guide screw placement, it comes with major drawbacks:
- ⚠️ Increased operative time
- ⚠️ High radiation exposure for surgeons and OT staff
- ⚠️ Limited visualization due to obstructions like shoulder girdles
- ⚠️ Increased cancer and cardiovascular risk due to radiation
Why CT-Based Navigation is the Better Alternative
CT-based navigation (like easyNav) eliminates many of these limitations:
- 📌 Radiation-free surgery for the surgeon and staff
- 📌 Better clarity in axial, sagittal, and coronal planes
- 📌 Accurate axial views preferred for screw fixation
- 📌 Real-time tool guidance in 3D
- 📌 Fast and efficient registration
- 📌 Reduced operative time
This approach especially benefits elderly patients with low bone density, allowing for better visualization of landmarks and increased fixation accuracy.
Final Thoughts
Using Spine 3D navigation not only enhances surgical precision but also:
- Improves safety
- Minimizes rework
- Reduces radiation risk
- Leads to better post-surgical recovery
For neurosurgeons and spine specialists, CT-based navigation is a transformative technology in managing complex spinal cases.
